If you have a homepage, commercial server or files located remotely, it's paramount that this server doesn't go down. Often we'll wait until someone complains before we even realise there is a problem and, by then, our website or server may have been down for hours. If you make your money from web sales, you may have lost potential revenue during this period.
SiteUp 1.1 is a free lightweight tool that you can use to monitor an external site to see if it's still up and running. It's a basic tool an ideal if you have your website stored remotely and need to check it's still online. It's not so good if you run a FTP server on a remote host and need to login to check it's still working. For this, you'll need a more advanced server-checking tool such as Simple Server Monitor.
